    Abstract: The formation of a high-quality image at a resolution at which a dot size is smaller than the diameter of a laser beam is attained at a low cost. When an exposure operation is carried out by increasing an optical intensity of a laser beam to a level higher than that of a steady-state optical intensity thereof by utilizing a difference, which is ascribed to an exposure rate of a photosensitive body, in the condition of a latent image formed, the depth and width of a latent image, which were small in all related art cases, can be increased to high levels. Therefore, overshoot is generated at the LD lighting starting time to increase the optical intensity at a rising edge of the laser beam to a level higher than that of a steady-state optical intensity thereof, whereby a height to width ratio and the reproducibility of one dot and a halftone in a case where the resolution is smaller than the diameter of the laser beam can be improved.

    Abstract: Digital image data of high resolution are obtained by synthesizing the scanning signals of two scanners, which scan an original document with mutually different lower resolutions. The synthesis includes transforming the scan signals of the first scanner into a first spectrum and transforming the scan signals of the second scanner into a second spectrum, superposing in predetermined manner versions of the first and second spectrum shifted over the spectral axis, and deriving a third spectrum from the result thereof. Retransformation of the third spectrum produces digital image data with a high resolution.

    Abstract: A system and method of deflecting a laser beam in a laser printer for providing enhanced resolution and reduced banding effects. Specifically, to enhance resolution, the laser beam is borrowed (deflected) from a white space area adjacent an image to double resolution at the edges of the image. Similarly, banding is reduced by deflecting the beam to compensate for drum rotational and translational errors. The beam is deflected using an electro-optic modulator placed between the laser diode and the scanning mirror. Encoders detect drum rotational errors and motion between the optics unit and the drum to provide a closed loop feedback system for reducing banding.
